PICKING` MEoHANl-SM FOR Looms.

PEGIFICATION foriningpart of Letters Patent No.I 729,62 6, dated June 2,1903.

Original application filed June Z8. 1962. Serial No. 113,672- D-ividhedand this aptlioationled November 1,1902. Serial No.1291686. (No modeL) y4 T all wiz/0m it 11m/y concern: i

Be it known that I, JOHN T. MEATS, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented an Improvement in Picking Mechanism forLooms, of which the following description, in connection With theaccompanying drawings, is a specification,

like characters on the drawings representing like parts.

This invention relates to looms, and more particularly to the pickingmechanism thereof and it has for its object the improvement in theoperation of such mechanism and simpliiication and cheapening of theconstruction of the same.

This application is a division of an application, Serial No. 113,672,filed by me on the 23th day of June, 1902, in which the pickingmechanism forming the subject-matter of this application is shown anddescribed, but not claimed.

The picking mechanism of my present invention relates more cspeciallytothat type wherein the picking-shaft and ball or roll, Which receivetheir motion from the usual picking-cam, are placed belouT the latter toavoid throwing oil upward against the Warps.V

Various means have been heretofore used to hold the ball or roll incontact with the picking-eam-such, for instance, as a tensionspringattached by a ho'ok'at one end to the picking-shaft and hooked at itsother end to a iXed part of the loom'.` So, too, the picking- Shaft hasbeen surrounded by a spring connected at one end to the shaft andiixedly held at its other end. In practice these structures have beenfound `to be lacking` in reliability, and they are also open to otherobjections, and one part of my invention has for its object theproduction of simple and effective means for overcoming theseobjections.

The novel features of my invention will be fully described' herein, andparticularly pointedout in the following claims.

Figure 1 is a right-hand-side elevation of a sufficient portion of aloom of usual construction to be understood with one embodiment of myinvention applied thereto; and Fig. 2

is a front elevation, partly broken out, of the mechanism illustratedinFig. 1.

The loom side 1, crank-shaft 2,l1aving fast and loose pulleys 3 el.thereon, the lay 5, la T- sword 6, Fig. 1, secured at its lower end tothe rock-shaft 7 the cam-shaft 8, having the picking-cam 9 fast thereon,the filling-fork 10, v-*eft-hammer 11, breast-bearer 12, and the holding-plate 13, having the shouldered notch l-l for the shipper, may be andare all of usual or Well-known construction and operate in Well-knownmanner.

Bearings 30 onthe `loom sidesupport the picking-shaft 31, mounted torock therein `and having an upturnedarm 32, (shown as integral with thepicking-shaft,) said arm being connected With the picker-stick by astrap or other usual connecting device34, the picker-stick being'mounted on the rock- `shaft 'Zin usual manner and drawn back by theusual spring 35, Figs. 1 and 2.

v A short arm 36 on the picking-shaft near its rear end has mounted uponit the picking- `roll 37, extended beneath and cooperating With theVperiphery ofthe picking-cam 9, the rotation of the latter controllingthe operation of the picker-stick by or through the rocking movement ofthe picking-shaft 31.

The front one of the picking-shaft bearings 30 is cast With a rearwardextension 38 above the picking-shaft and provided with a recess orpocket 39, in which is seated one end of a coiled compression-spring,the other end of the spring being seated in a pocket 40 in the end of ashort upturned arm L11, fast on or integral With the picking-shaft. Bythis construction I am ableto use a spring which is always incompression, (the spring keeping The construction herein describedimparts a greater smoothness and uniformity to the picking motion and isnot liable to get out of order or to deteriorate with use.

Having` described my invention, what I Claim as new, and desire tosecure by Letters Patent, is-

l. In a loom, the picking-cam, a pickingshaft mounted in iXed bearingsbelow the picking-cam and having an arm, a roll on said arm to cooperateWith the cam, a second, up turned arm on said picking-shaft having apocket, a fixed pocket opposed thereto, and a Compression-spring seatedat its ends in the said pockets and operating to maintain the roll ineoperative engagement With the pieking-Cam.

2. In a loom, the picking-cam, a pickingshaft mounted in right-angles tothe axis of rotation of the cam, iiXed bearings for said shaft, one ofthe bearings having an extension provided with a pocket, a roll carriedby the picking-shaft and engaged by the cam, a seoond arm on said shaft,upturned and provided with a pocket facing the pocket in the eXtension,and a compression-spring seated at its ends in the pockets, to maintainthe roll lifted in eoperative engagement With the cam.

In testimony whereof I have signed my name to this speoiiioation in .thepresence 0f tWo subscribing Witnesses.
